Best New Luxury Car Under $75,000: BMW has been billing itself as the “Ultimate Driving Machine” for years, and when it comes to the new 5 Series, we find it hard to disagree. An unparalleled combination of performance and luxury made it the clear choice for Best New Luxury Car under $75,000. Further cementing it as the winner is the choice of seven different trim levels ranging from the 230 hp, 3.0-liter, inline-six-powered 528i to the 500-horsepower, 5.0-liter V-10-powered M5. There is even a Sports Wagon version available as the 535xi which might also qualify the 2008 BMW 5 Series as the “Ultimate Cargo Machine.”
